What “1 mm of rain” means
Rainfall is measured as the depth of water that would cover flat ground if none drained away or evaporated. One millimeter over one square meter is exactly one liter of water, so 10 mm on a 100 m² roof is 1,000 liters.
How heavy is the rain?
Meteorologists usually describe intensity per hour: light rain is under 2.5 mm (0.1 in) per hour, moderate 2.5–7.6 mm (0.1–0.3 in), and heavy above 7.6 mm (0.3 in) per hour. Above 50 mm (2 in) per hour is violent and quickly causes flash flooding.
